Platform Engineer

About Us Waystone is a leading provider of institutional governance, administration, risk and compliance services to the asset management industry. With over 25 years’ experience, we support many of the world’s largest asset managers, providing a comprehensive range of specialist services from a global network of offices. The Platform Engineering team builds and operates Waystone’s engineering platform, spanning cloud infrastructure, CI/CD, observability, on-call and our internal developer portal. We provide the secure, automated foundations that the firm’s regulated services run on. We are looking for a Platform Engineer to help scale this platform through standardised, automated and compliant patterns, accelerating delivery for our development delivery teams while raising operational resilience across the estate. We are a cross-skilled team by design: rather than narrow specialisation, we want every engineer able to work across the platform, giving us broader coverage, resilience and shared ownership. Key Responsibilities Take ownership of larger, moderately complex pieces of platform work, setting objectives and delivering against project goals with a direct impact on team results.Design, implement and maintain scalable cloud infrastructure patterns and reusable Terraform modules across Azure, AWS and OCI, with a primary focus on Azure.Develop and maintain Infrastructure as Code (IaC) libraries to ensure consistent, compliant and repeatable environments across all cloud providers.Build and support CI/CD and deployment automation using GitHub Actions, Octopus Deploy and ArgoCD, and configuration management using Ansible and Octopus Deploy.Support and enable development delivery teams – provisioning autonomous environments and reducing deployment friction while maintaining guardrails and separation of duties.Provide operational support for containerised and micro-service workloads on Azure Kubernetes Service (AKS), maintaining high availability and reliability.Manage core infrastructure lifecycle tasks – vulnerability remediation and patching, upgrades, scaling and decommissioning across the Windows and Linux estate.Drive the adoption of cloud governance policies, security standards and architectural best practice, and help maintain continuous compliance evidence against the firm’s obligations (SOC 2, ISO 27001, GDPR, DORA).Contribute to observability and monitoring across the estate, and to incident response and on-call, including troubleshooting and root cause analysis that drives systemic improvement.Support disaster recovery testing to validate recovery plans and ensure rapid, reliable restoration of services.Identify and recommend improvements to systems, processes and infrastructure patterns to improve operational resilience, performance and cost efficiency.Explain and advocate technical approaches to development delivery teams and colleagues across IT, influencing platform practices and standards at an operational level.Provide guidance, code review and support to junior engineers, helping them develop across the platform.Document infrastructure blueprints, standards and standard operating procedures in Confluence and our internal Platform Portal to enable self-service.Participate in the on-call rota to support critical infrastructure services. Essential Knowledge & Experience University degree or equivalent practical experience, with a minimum of three years’ experience as a Platform Engineer, Cloud Infrastructure Engineer, DevOps Engineer or similar role.Strong experience designing and implementing infrastructure in Azure and AWS.Deep, hands-on expertise with Infrastructure as Code using Terraform.Experience building and debugging CI/CD and deployment pipelines (e.g. GitHub Actions, Octopus Deploy, Azure DevOps or similar).Strong Windows OS management in cloud environments; solid Linux fundamentals (deeper experience a plus).Proficient in a scripting language such as PowerShell, with experience automating operational workflows.Sound understanding of cloud security principles, identity and access management (Entra ID / IAM) and network security.Understanding of application architectures and CI/CD workflows, and how infrastructure aligns with them.Experience working closely with development delivery teams in an agile environment, using tooling such as Jira and Confluence to manage and track work.Excellent analytical, problem-solving and communication skills, with the ability to explain technical decisions to non-technical stakeholders.AI-literate, with the ability to adopt and apply AI-assisted engineering tooling (e.g. GitHub Copilot, AI coding assistants and agents) to accelerate delivery, automation and documentation, and a willingness to keep pace with an evolving AI toolset.Able to manage multiple concurrent workstreams – balancing project delivery, BAU and support commitments – prioritising effectively and working independently across competing demands.Able to participate in the on-call rota – on-call is a requirement of this role. Desirable Experience operating in a regulated financial services or otherwise highly governed environment.Certification in Azure, AWS or DevOps practices.Hands-on experience with Kubernetes (AKS), ArgoCD and containerised services.Experience with Ansible for configuration management and DR tooling.Familiarity with Oracle Cloud Infrastructure (OCI).Knowledge of FinOps and cloud cost-management best practice.Experience integrating AI or agentic tooling into engineering workflows (e.g. IaC generation, automated remediation, or documentation).Exposure to compliance-evidence or governance tooling and incident-management tooling. Additional Information This is a hybrid role, with attendance at our Leeds office once a month.Participation in the on-call rota is a requirement of this role; standing on-call allowances apply.Opportunities for professional growth, including certifications in Azure, AWS and DevOps practices, within a deliberately cross-skilled team.You will join a global, collaborative team that values innovation, ownership and continuous learning, with a direct impact on the resilience of the firm’s platforms.
